maxonik [38]

Answer:

The number of nickels are 10 and number of pennies are 5.

Step-by-step explanation:

Given:

Elijah has $0.55 worth of pennies and nickels.

He has twice as many nickels as pennies.

Now, to determine the number of pennies and the number of nickels that Elijah has.

Let the number of nickels be $x.$

And the number of pennies be $y.$

As given that he has twice as many nickels as pennies.

$2y=x$

$x=2y.$ ......(1)

The total worth of worth of pennies and nickels = $0.55.

As, the value of a penny = $0.01.

And the value of a nickel = $0.05.

Now, to get the number of pennies and the number of nickels that Elijah has:

$0.05(x)+0.01(y)=0.55$

Putting the value of $x$ from equation (1):

$0.05(2y)+0.01(y)=0.55$

$0.10y+0.01y=0.55$

$0.11y=0.55$

Dividing both sides by 0.11 we get:

$y=5.$

The number of pennies = 5.

Now, putting the value of $y$ in equation ( 1 ) we get:

$x=2y\\x=2\times 5\\x=10.$

The number of nickels = 10.

Therefore, the number of nickels are 10 and number of pennies are 5.

The next larger ten thousand is 70,000 .
The next smaller ten thousand is 60,000 .
67,000 is closer to 70,000 than it is to 60,000 .
So 70,000 is the nearest ten thousand.

Can anyone show me how to divide 931/7

Inessa [10]

(You go from left to right)
(Dividend is 931, divisor is 7)
Step 1: Look for a number smaller than 9 that is divisible by 7. 7 is the only one which is smaller than 9 and is divisible by 7. Now that you know 7*1=7, you put 1 above 931 (Dividend)
Step 2: You subtract that number from the number in tens place. And bring the leftover down.
Step 3: You repeat Step 1 and 2 until either you get a remainder of 0 or the remainder in smaller than the divisor (in this case 7)
(Therefore 931/7=133, quotient=133, remainder=0)
^Hope this helps.
